Wavelet-based Edge Multiscale Finite Element Method for Helmholtz problems in perforated domains

Shubin Fu, Guanglian Li, Richard Craster +1

We introduce a new efficient algorithm for Helmholtz problems in perforated domains with the design of the scheme allowing for possibly large wavenumbers. Our method is based upon…
